Line Trace Questions

I have this setup to move a Niagara System lightning bolt based on landscape height and random X and Y locations. It will place the lightning bolt at the correct Z location on the “floor cube”. However, it does not “hit” any other cubes or objects. I am in the basic 3rd person level setup when starting a new project. I am trying to get it to hit anything. All the cubes derive from the same base mesh cube. What am I not understanding with the line trace? At this point, I am not even sure why it does hit the floor cube, even when the floor cube location is changed it still works. I cannot find any difference between the cubes besides location and scale. Thank you in advance if you can help with this. :slight_smile:
